Title: Acoustical insulation material containing fine thermoplastic fibers.
Inventor: FRAZIER NINA
IPC: E04B1/84
Filed: 2003-04-30
Abstract: The present invention relates an acoustical insulation material for sound attenuation containing a nonwoven web. Surprisingly, it has been discovered that an acoustical insulation material made from a nonwoven web of thermoplastic fibers having an average fiber diameter of less than about 7 microns, wherein the acoustical insulation has a thickness less than about 3 mm and a density of greater than about 50 kg/m3 is effective as a sound insulation material.
